Mike, It is a YJ, but it may be the same issue you are talking about. I
purchased a service shop manual ... should get here by wednesday. It
seems to be a gray issue on how to properly troubleshoot a sensor.
Somewhere I heard to measure 5 volts... but where and do I have to
pierce the insulation while the connector is connected is not
disclosed. Hope the shop manual is worth the $100!

Actually, if it is pulsed at 5 volts, I should be able to see it on one
of the wires as I'm turning the gear, I have an old scopemeter to
watch. Of course, I'm assuming the sensor does not have to be grounded
to the transfer case and my vehicle works like a TJ.

I'm betting the 3 pins are volts input, pulsed volts output, and
ground....

They could be 5 volt pulses. The sensor itself puts out the volt
pulse. They only happen when it is spinning so I think a bench test
might be in order?

Basically I would put the meter on pin 1 and 2 and hand spin it to see
if it pulses. Or 1 and 3 or 2 and 3. It is something like some of the
distributor units, they show a pulse on a meter when hand moved.
